composite with 3d element

Hello,

I have a project with a 3d objet, a fbx imported with animation, light and camera.
When i want to composite it with a constant color, it seems the background is not totally tranparent. the color of the constant color is darker that it should be.
Any idea?

thanks!

Without seeing your FBX it’s hard to know what’s happening here. Can post a file so we can have a look?

are you just trying to texture your 3d object with a constant red color unaffected by light, having your object be red and the background be transparent? If so you just need a basic render network containing a 3d object textured with a constant.
